Trying to fix GMod 12 script

So basically, I’ve been trying to fix up an old GMod 12 script for GMod 13 and came upon this:

[lua]if not ulx.songplayer_videos then
ulx.songplayer_videos = {}
if file.Exists( songplayer_video_file ) then
ulx.songplayer_videos = ULib.parseKeyValues( file.Read( songplayer_video_file ) )

What replaced file.Exists in gmod13?

It’s still there but it needs a 2nd argument.
